iPhone cellular data is very slow

Slow cellular is from weak signal, network congestion, your carrier throttling you after high data use, or a settings glitch. Try toggling Airplane Mode, checking signal strength, and resetting network settings.

Cellular data speed depends on your signal strength, how many people are using the network in your area, and what network you're on (4G or 5G). Slow speeds come from one of these: weak signal, too many people on the network, a settings problem, or your carrier throttling after high data use. We'll test each one.

Risk: Low ⏱ 10-20 minutes Beginner
⚡ Before you start
  • Check how many bars you have. 1-2 bars naturally means slower speeds
  • Is it slow everywhere you go or just in certain locations?
  • Does WiFi work fast when you're near it? That tells you if the problem is cellular or your whole connection
  • Check if you've used a lot of data this month. Your carrier can be throttling you
